hey Dan,
I hope you are feeling better. Since RR-Track has all of the accessories, I built your layout. Using modern O31 switches, I only find one joint, where you may have to cut and two joints that will be wiggle fits.
Here's the 3D - some accessories were close and I slide them along one way or the other. The AF log loader didn't fit where you had it. Doesn't the culvert need both loader and unloader? A light tower, some billboards and yard lights and you are in business!
